Compliance: Required as indicated after the effective date of this AD, unless already accomplished.

To prevent failures in the rudder control system, accomplish the following:

(a) Within the next 25 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished, replace all DIN specification 055, 6 by 7 inch rudder cables with a diameter of 2.55 mm (.098 in.) having a hemp core, with a 7 by 7, 3/32 inch cable, manufactured in accordance with MIL-W-83420D or MIL-W-1511A, with cable connections constructed in accordance with Actions 2 of Hansjorg Streifeneder Technical Note Nos. 201-26, 301-33, 401- 20, 501-4, all dated March 15, 1987.

NOTE: The replacement cables may have been installed pursuant to superseded AD 71- 16-06, Amendment 39-1253, or superseded AD 88-07-05, Amendment 39-5865.

(b) Within the next 100 hours TIS after the replacement of the cables required in paragraph (a) of this AD or within the next 100 hours after the effective date of this AD, whichever is applicable, and thereafter at intervals not to exceed 100 hours TIS, visually inspect the rudder cables for wear, fraying, corrosion, twisting or other damage. If damaged cables are found, prior to further flight, replace the damaged cables with cables and connections as specified in paragraph (a) of this AD.

(c) An alternative method of compliance or adjustment of the initial or repetitive compliance times that provides an equivalent level of safety may be approved by the Manager, Brussels Aircraft Certification Office, Europe, Africa, and Middle East Office, FAA, c/o American Embassy 15 Rue de la Loi, B-1000 Brussels, Belgium. The request should be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Brussels Aircraft Certification Office.

(d) All persons affected by this directive may obtain copies of the documents referred to herein upon request to Hansjorg Streifeneder, Glasflaser Flugzeug Service GmbH, Hofener Weg, D-7431 Grabenstetten, Federal Republic of Germany; or may examine these documents at the FAA, Central Region, Office of the Assistant Chief Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106.
